The yield and nutritive value of maize and their mixtures for harvesting succulent fodder in conditions of central Yakutia

Abstract

Corn takes the leading place among silage cultures. The silo prepared from her in a phase of dairy and wax ripeness has good digestibility. On a forage there are cleaning which are also remaining later on grain dry leaves, stalks and cores of ears. The practical value has use of corn stalks which in comparison with straw of other grain crops differ in the increased protein content and the best digestibility. Objects of researches are the following grades of perspective one-year forage crops - corn a grade Katerina, peas Yamal, Vika summer - Ob 25. Joint cultivation of forage crops allows to receive steadier harvests, to increase nutritiousness and eatability of a forage. This results from the fact that different plants unequally react to adverse conditions. High rates on productivity from the mixed crops were provided by corn option with peas of 38,5 t/hectare, at the same time the maintenance of a digested protein on 1 fodder unit has made 221 g, 0,65 sterns unit. On nutritional value the best option is corn with Vika summer with the high content of digested protein of 1 fodder unit of 234 g, 0,66 sterns unit, at the same time net income has made 24 969 rubles, profitability of 126%.
